如何在使用鍵盤移動光標後，如何比較二維數組上的光標位置？

Question

我有一個在屏幕上繪製文本地圖的二維數組，我使用'WASD'在屏幕上移動一個字符。 我想測試地圖限制，以便角色不會出界。

任何線索？

這裏是我的代碼：

static void Main(string[] args) 
    { 
     bool GameOver = false; 
     int playerX = 1; 
     int playerY = 1; 
     char[,] myCharArray = new char[16, 8]; 
     string[] lol = new string[8]; 
     lol[0] = "----------------"; 
     lol[1] = "-    -"; 
     lol[2] = "-    -"; 
     lol[3] = "-    -"; 
     lol[4] = "-    -"; 
     lol[5] = "-    -"; 
     lol[6] = "-    -"; 
     lol[7] = "----------------"; 

     for (int i = 0; i < 8; i++) 
     { 
      char[] letters = lol[i].ToCharArray(); 

      for (int j = 0; j < 16; j++) 
      { 
       myCharArray[j, i] = letters[j]; 
      } 
     } 

     do 
     { 
      for (int i = 0; i < 8; i++) 
      { 
       for (int j = 0; j < 16; j++) 
       { 
        if (playerX == j && playerY == i) 
        { 
         Console.Write('*'); 
        } 
        else 
        { 
         Console.Write(myCharArray[j, i]); 
        } 
      } 
      Console.WriteLine(); 
      } 

      ConsoleKeyInfo pressedKey = Console.ReadKey(); 
      Console.WriteLine(pressedKey.Key.ToString()); 
      if (pressedKey.Key.ToString() == "A") 
      {      
       playerX--; 
      } 
      if (pressedKey.Key.ToString() == "S") 
      { 
       playerY++; 
      } 
      if (pressedKey.Key.ToString() == "D") 
      { 
       playerX++; 
      } 
      if (pressedKey.Key.ToString() == "W") 
      { 
       playerY--; 
      } 
      Console.Clear(); 
     } while (GameOver == false); 

    }

如果條件在這裏：

if (pressedKey.Key.ToString() == "A") 
      { 
       //check if move left is possible 
       if(playerX != 0)     
        playerX--; 
      }
